Samurai polyhedron: only in the east could they come up with such a subtle combination of volumetric shapes and flat lines of color.

The polyhedron is one of the stellate forms of the icosahedron.
On the bas of the icosahedron diagram, you can see the structure of the polyhedron.
The face of the polyhedron are three triangles highlighted in red in the figure.
A polyhedron consists of 20 groups of such triangles.
The shape of the triangle is as follows:
The classic color of this polyhedron is the color combination for the icosahedron. 20 groups of faces with 3 triangles in each.
We decided to offer our version of coloring, the same for all 60 triangles. This is a red stripe in the center of the triangle.
To build with this color combination, you should use a net:
